IMPROVEMENT m DOOR-CHECKS.

Specification forming part of Letters Patent No. 174,l95, dated February29, 1876; application filed January 3, 1876.

To all whom it may concern Be it known that I, EDSELL W. CHAMBER- LAIN,of Sullivan, Ashland county, Ohio, have invented a new and Improved DoorCheck and Holder, of which the following is a specification:

The invention consists in forming a reversible door-check of two pieces,one of which has a pivot, base-plate, and check-studs, and the other alatch and check; the whole to be used in connection with a spring, ashereinafter more fully described and definitely claimed.

Figure 1 is a top view of a door and my improved check and holder, andFig. 2 is a side elevation.

Similar letters of reference indicate corresponding parts.

Ais the-door; B, the latch; G, the catch; D, the check; E, the spring;F, the pivot, and G the support for the pivot. The edge of the doorstrikes against the beveled nose of the catch and swings it back, andthe spring throws itforward again when the door passes the catch. Assoon as the door passes the catch, it strikes against the check D and isstopped. Instead of catching the edge of the door, a piece of metal maybe attached to the side of the door for the latch to work on.

The spring may be contrived in different ways, and the support for thepivot may be contrived for attaching to the base of the' wall orpartition instead of the floor.

H represents a coupleof check-studs that may be used to limit the swingof the catch in either direction.

I am aware that pivoted-latch door-checks are not new; but 1 make mineof only two castings, ready to receive the spring and to be applied todoorwayswithout drill, file, or other tool, at very small expense; also,so as to be reversible, and thus serve as a right or left check bysimply changingsides. Hence,

What I claim i A reversible door-check, cast or otherwise formed of twopieces, one having pivot F, base-place G, and check-studs H, and theother a reversible latch-piece B, having latch O, and check D,applicable in connection with spring E, as and for the purposespecified.
